ROLLER-BEARING.

SPECIFICATION forming part of Letters Patent No. 643,122, dated February 13, 1900. Application filed September 15, 1899. serial No.730,645. (N0 model.)

' tion.

This invention relates to improvements in roller-bearings.

The objects of the invention are, first, to provide an improved roller-bearing in which the rolls are retained in true alinement with the line of the axle or shaft, and are so guided and supported that they preserve their contour and are not liable to become flat-v tened or otherwise deformed; second, to provide an improved boxing easy to manufacture which shall be effective in operation; third, to provide an improved means of retaining the box effectivelyin position, which shall make it adjustable to hubs of different lengths; fourth to provide, in connection with a roller-bearing, improved means of ex cluding the dust therefrom, and, fifth, to provide in a roller-bearing improved means of admitting and retaining the oil. Further objects will definitely appear in the detailed description to follow. I accomplish these objects of my invention by the devices and means described in this specification.

The invention is clearly defined, and pointed out in the claims.

A structure fully embodying the features of my invention is fully illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is a vertical longitudinal sectional view through a hub, taken on a line corresponding to lines 1 1 of Figs. 2 and 3, the axle and'rollers being shown in full lines. Fig. 2 is an end elevation of the structure appearing in Fig. 1. Fig. 3 is avertical transverse detail sectional elevation taken on a line corresponding to line 33 of Fig. 1.

In the drawings similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A is a cylindrical axle havingthe usual collar A thereon.

B is the hub.

F is the boxing, made, preferably, of a drawnsteel tube. On the inner end a flanged plate 0 is provided, which is secured thereto by screw-threads, and a flange 0 projects inwardly to serve as a stop or shoulder to retain the antifriction-rolls J in position. On the opposite end of the tube or box F is secured a screw-threaded plate E, which is adjustable to secure the axle-box in any length of hub. A flanged plate G is provided, which screws onto or is otherwise secured to the end of the box F and serves to retain the rollers at the outer end.

The structure is retained in position on the axle or shaft by a nut I of the usual construction'or by other suitable means-as, for instance, a cotter-pin. Secured to the plate E and adapted to engage screw-threadsthereon is a dust-cap H, which entirely closes the outer end of the bearing. A dust collar or band D is provided to screw onto suitable threads on the plate 0 on the inner end,which embraces the axle or shaft A closely. Between this band and the collar A is a pad of felt L to serve to retain oil within the bearing and also prevent the entrance of dust at that point. The plates E and O are also preferably secured to' the hub by suitable bolts K, extending lengthwise through the same, though it is possible to dispense with these in practice, it being found, however, that they serve a very useful purpose in preventing any possibility of the box becoming loosened. I provide an oil-hole P, extending through the nut 1 into the axle A and then down to the surface of the axle to deliver oil into the boxing, where it is securely retained and serves to keep all of the rolls thoroughly lubricated. I desire to say in this connection that in order to secure satisfactory results with a rollerbearing the rolls J must not only impinge with the axle A and the boxing F, but they must impinge against each other, forin this way the several rolls serve as guides for each other and prevent the same from being thrown out of alinement, and consequently any bending of the same is avoided, and by having them arranged thus closely together it is impossible to apply sufficient weight to the axle to succeed in flattening the rolls, and, again, when the rolls impinge upon each other in this way when any one of the rolls turns the motion is imparted to the others, which prevents any of them becoming stuck fast and worn flat on one side. This tight fitting also by engaging the axle or shaft for the entire length of the bearing prevents the same being accidentally sprung out of position or prevents the springing of the axle, as it is called, and by the rollers fitting thus tightly upon the axle they serve to retain the same much more securely than a plain bearing on account of the closer contact, and this avoids almost completely the end motion of the same, a tight fit being possible in this connection, owing to the greatly-reduced friction due to the special construction. That this is true is evidenced by the fact that in actual practice a light cotter-pin has been found amply sufficient to retain the hub in position where very heavy work was done. I desire to state also that my special construction enables the insertion of the rolls thus tightly in position, for by removing the cap G the space is entirely free, and the rolls can be inserted one at a time and crowded very tightly into position.

It will be observed that with the annular flange at each end of the boxing the boxing becomes a receptacle for oil, so that all of the rolls and the axle are more completelylubricated than they are in any other style of axle box or bearing. By this means the rollers are each successively immersed in oil, and more complete lubrication is therefore not possible.

I desire to say also that while I have shown this complete structure in its most approved form I am aware that it can be greatly varied without departing from my invention. Tht flange at one end of the box might be made integral with the box, though I prefer to make it as shown. For ordinary use the dust-cap and dust-band might be entirely omitted. In fact, I have used the same in this way with merely a cotter-pin to retain the bearing in position.

I desire to state also that While the particular construction I have shown enables the tight insertion of the antifriction-rollers in the bearing, thus securing the impinging which is so essential, I am aware that the rollers might be fitted and inserted in other ways and secure the same tight fit, though I believe the exactstructure which I have shown to be the most practical for that purpose. I believe that the flanges on each end of the boxing extending inwardly to retain the rolls which are fitted tightly in position would be sufficient to secure a very practical bearing when any suitable stops or collars are placed outside of the same to retain the hub or other revolving part in position. The boxing referred to need not be a separate part, but may be formed integral with the hub or with the wheel-center when no hub is present.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is
